“But they that wait upon the Lord shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; and they shall walk, and not faint.”
—Isaiah 40:31 (KJV)
Waiting is rarely easy.
We wait for answers to prayer. We wait for direction. We wait for healing, restoration, opportunity, or clarity. Sometimes we wait for circumstances to change, and sometimes we simply wait for the strength to face another day.
During those seasons, it can feel as though everyone else is moving forward while we remain standing still. We may begin to wonder whether God sees us, hears us, or remembers what we have placed before Him.
Isaiah 40:31 speaks directly into that weariness. It reminds us that waiting on God is not wasted time. It is often where our dependence deepens, our faith matures, and our strength is renewed.
When We Reach the End of Our Strength
Isaiah’s words were given to people who were tired and discouraged. They felt overlooked and wondered whether their circumstances had escaped God’s attention.
Yet Isaiah reminds them that God does not become tired or overwhelmed. His understanding has no limit, and His strength never runs out. Even the strongest people eventually grow weary, but God remains steady.
This matters because we often approach difficult seasons by trying harder. We carry the burden, search for the answer, and work to produce the outcome we believe we need. There is nothing wrong with acting faithfully, but there comes a point when determination becomes self-reliance.
God never asked us to be our own source of strength.
Isaiah 40:31 is not a promise that faithful people will never become tired. It is a promise that weariness does not have to be the end of the story. When our strength is depleted, God invites us to depend on His.
What Does It Mean to Wait on the Lord?
Waiting on the Lord is not the same as sitting back and doing nothing. Biblical waiting is active trust.
It means continuing to believe God is faithful before we can see what He is doing. It means seeking Him in prayer, remaining grounded in His Word, and taking the next faithful step even when we cannot see the entire path.
Waiting also requires surrender. We are not only asked to trust God’s answer; we are asked to trust His timing.
That may be the more difficult part.
We often know what we want God to do and when we would like Him to do it. When His timing differs from ours, we can interpret the delay as absence. But God’s silence does not mean He is uninvolved. The waiting season may be doing important work within us—exposing what we depend on, reshaping our desires, and teaching us to recognize His presence apart from our preferred outcome.
Waiting on God is not passive resignation. It is confident dependence on the character of the One for whom we wait.
They Shall Renew Their Strength
Notice that Isaiah does not say those who wait on the Lord will discover more strength within themselves. Their strength will be renewed.
God is the source of the renewal.
Sometimes that renewal arrives as a dramatic breakthrough. At other times, it looks like unexpected peace in the middle of unresolved circumstances. It may be courage to have a difficult conversation, patience to remain faithful, wisdom for the next decision, or enough grace to make it through today.
We often ask God for enough strength to finish the entire journey. He frequently gives us what we need for the next step.
This keeps us close to Him. It reminds us that faith is not a one-time decision to rely on God but a daily posture of returning to Him.
Reflection
Where have you grown weary while waiting?
Are you relying on God’s strength, or are you trying to carry the situation through your own effort?
What is one faithful step you can take today while leaving the timing and outcome in God’s hands?
